An Egyptian commission investigating the deaths of protesters during the uprising that toppled Hosni Mubarak in 2011 says the former president knew the extent of the protests and the crackdown against them.

The commission says Mubarak watched live video feeds of the protests and the brutal response of his security forces.

Mubarak is already serving a life sentence over the deaths of hundreds of protesters.

But he has been convicted of failing to stop the killings, not ordering them.

The report of the fact-finding panel could increase pressure on authorities for a retrial of the 84-year-old former president.

The report has not been made public but several members of the commission have spoken about its findings.

It was commissioned by Egyptian President Muhammad Morsi soon after he took office in June.
